ROTARY CLIPPER,

To all whom t may concern:

Be it known that I, LESTER B. MYERS, a citizen of the United States, residing at Monte Vista, in the county of Rio Grande and State of Colorado, have invented certain new and useful;`V` Improvements in Rotary Clippers, of which the following is a specification. Y

This invention relates to improvements in clippers and itis the principal object of the invention to provide a motor operated clipper emplOyinga-rOtatable knife supported in suitable antgfrictional bearings'and having connectionwith permit the transmission of rotary motion thereto. j

Other objects will be in part obvious and in part pointed out hereinafter.

The improvements in the detailsand arrangement of parts will be apparent from an drawings, in connection with the specific description hereinafter contained, and wherein the preferred embodiment of the invention is dis-V closed for the purpose of imparting a `full understanding of the same.

ln the drawings:

Figure 1 is a vertical section through the improved clipper,

Fig. 2 is a horizontal section therethrough, and

Fig. 3 is a detail in elevation of the connection between the drive shaft and the rotary blade. A

Having more` particular reference to the drawings, in connection with which like reference characters will designate corresponding parts throughout `the several views, l

represents the substantially U-shaped framev of the clipper construction, the same having a laterally extending screw threaded nipple 2 formed l thereon a-nd vadapted to receive a handle 3, said handle having a longitudinally disposed bore formed therein com- -municating with the bore in said nipple 2 for a purpose hereinafter apparent. In this connection, it is to be' noted ,that the lower portion of the frame 1 is of less length than the upper or top side thereof ar! i is reduced or shouldered as at 3 to permit an immovable blade e to be secured thereto, said blade being apertured forreceiving a plurality of screws 5- therethrough the threaded Shanks the reduced endl 3 of the frame. As will be Specification of Letters Patent.

noted, the cutting blade the usual serrated cutting edge designated by the numeral 6 a-nd between which Athe matter to be cut is passed. v

Rotatably mounted on the up er face of? the blade 4 is a rotatable multilade knife 7 having a concentrically located aperture which receives therethrough a boss 8 formed on the adjacent face of said blade 4, the upper end of the boss being' formed witha seat for'receiving a suitable anti-frictional bearing element 9 therein. As will be noted, the various blades of the rotatable knife 7 are so arranged as'to move over the serrated cutting edge 6 of the immovable knife or blade 4 in sequential order,l tlius engaging and cutting the matter passing therebetween.

A motor `1.0 is secured to the rear portion of the frame 1 by bolts 11 or similar fastening devices which as will be noted are passed through the apertured flanges thereof and has its armature shaft 12 extended, the upper end of the same beingcut as at 13 'for receiving an anti-frictio-nal bearing element 11, which element is in turn engaged by an adjustable screw threaded bearingl having the under side of the head thereof serrated as at 16 and engaged by a spring vpawl 17 whereby to prevent reverse rotation -of the same subsequently to adjustment-. The

lower end ofthe armature shaft 12 is cuppedlas at 18 and engaged with the antiffrictional 7 is effected. Attention is invited to the vfact that clockwise rotation ofthe shaft will have a 'tendencyto move the coupling 19 downwardly on account of the screw threads, thus preventing accidental release of the rotary knife during operation. Furthermore, 'the knife the coupling-19 has merely to be rotated in an the -fingers thereof are disengaged from the apertures.

A closure plate v2()` is securedto the forward portion of thev frame and has the lower marginal portion thereof extended down wardly to a point. in proximity to the rotatable knife 7 for an obvious purpose.

If desired, the conductors 21 for the motor a driving .connectionI Y between the motor 10 and the rotatable knife 4 is provided with can be passed from the several terminals thereof through the nipple and the handle'A 3 into engagement with the source of energy,

a Suitable circuit closing means being interposed therein to control the passage of current to the motor.

In operation, the adjustable bearing l5 is properly adjusted with relation to the upper end of the armature shaft l2 and the motor .l0 is then energized. Upon rotation of the armature shaft, rotary motion will be of course transmiteed to the rotary knife 7 and as a consequence, the matter passing between the serrated cutting edge 6 of the immovable knife 4 will be severed thereby. The sage of the mattei' severed by the rotatable knife into the'frame and the anti-frictional bearings provided the armature shaft l2 will be prevented due to thel provisionof the plate 20, the same serving as a form of guard or delector.

Manifestly, the construction shown is capable of considerable modication and such modification as is within the scope of my claims, I consider within the spirit of my invention.

I claim:

1. In a clipper, a'frame,

a'. relatively statio-nary knife carried by the frame, a rotary knife bearingagainst the relatively station-k ary knife, a motor supported in lthe frame,

said motor including an armature shaft, for a bearing 4f of the shaft carried by the relatively stationa-ry knife and extending axially through and spaced from the rotar knife, said rotary knife being provided wit i a series of apertures, and a coupling inem*l ber movably secured to the terminal of the shaft provided with a series of fingers engaging in the apertures in .the rotary knife for driving the latter.

2. In a clipper, a frame, a relatively stationary knife carried by the frame, a rotary knife bearing against the relativelyA stationary knife, a motor supported in the frame,

including an armature shaft having a screw threaded terminal, a bearing for the shaft carried by the relative stationary knife, and extending axially through and spaced from the rotary knife, said rotary knife being provided with a series of a ertures, an internally screw threaded coup ing member movably mounted on the screw threaded. terminal of the shaft and tending to move downwardly on clockwise rotation of the shaft and on' account of the action of the screw threads, and fingers on the coupling engaging in the tary knife whereby to drive ,the latter.

In testimony whereof, I aiiix my signature hereto.
